At the interior of the fixture, and at suitable points at spacedintervals throughout the length thereof, is a combined n'nillion andwiring box 1.7. This element is of substantially rectangular formation,and is in the form of a frame, one or more oi these rnullions beingemployed in accordance with the length of the fixture, =d each beingdesigned to brace the fixture and to afford proper sup port for thetrontand rear walls and As seen in Figure 6, the baseot the element 17 has atransversely extending head 18 formed thereon, the edges of the base atopr s" .i sait. cad 'mhlig sacs Jone scles ot l b lT l l e t to supportthe contiguous ends of the glass panels 16. At the upper end Oil: theelement 17 is a boxlilre receptacle l9,'which consti tutes a wiring box.The opposite walls it the receptacle 19 are provided with gned openings20 at the exterior oi each of which is arranged'a hublilte flange 21.The openings 20 receive the bases of oppositely projecting insulatedlamp sockets 22 which seat against said flanges 21, and are sutahly sccured in these openings to support the necessary lan'lps tor giving therequisite illumination to the fixture. To eaco. ot the sockets 22 thereis suitably connected a supporting trains 23 for reflectors tor theseveral lamps, said frames 23 being provided vith slotted attaching;ears 24 which cooperate with t'astening screws 25 through the inediun'iof which the sockets 22 and the frames 23 are secured to the flanges 21.r

The opposite sides of the walls of the re ceptacles 19, at the endportions thereof, are provided with oppositely disposed attaching lugs26, said lugs 26 each. being provided with an elon ated slot 27 forreceiving iiasteningig screws .28, and the horizontal flanges of therectangular offsets 12 of the front and rear walls 10 and 11 seat uponsaid lugs 26 and are secured thereto by the bolts @bvi- -JL: ously, theslots 27 afl'ord adjustment of the bolts to provid for adjustment ofhllO side walls 10 and 11. in relation to the element 17. The upper.edges of the walls of the receptacle 19 are also provided with alignednotches 29 into which are titted the ends of flanged wirewaysor troughs30 wherein are positioned the electrical conductors included in thewiring connections of the lit re. While affording access to the Wiringconnections from the top oi": the fixture, the wire ways 30 concealthese connections the in terior of the fixture, so that the wiring-3,connections are not exposed at such interio I Each side wall of thereceptacle l9 h s a verticalrib 31 at its exterior, and to out: otsaidribs 31 is connected :1 fastenin new 32 which penetrates, coverplate 33 tin ou h the medium of which the top of the fixture is closed.This cover plate 03 has depending marginal flanges 3% which tit over theupwardly extending flanges 1d of the front and rear walls 16 and 11,thereby presenting a finished joint at these points, and effectuallyconcealing the flanges 14 from view. ()bviously, the plate 33 covers thewireways 30, so that uccessto the interior of these wireways cannot behad except upon removal of the cover plate lVithin the receptacle 19 islocated also a suitable switching device 35. This may be of the pullchain type, or it may be of any other approved construction. This switching device controls the wiring connections for switching on and oil theseveral lamps connected to the various sockets 22.

At the terminal portions or the fixture are located end caps 36. Thesecaps also are of paneled formation to impart an ornate appearance to theends of the fixture, and the sides and bottom oi paid caps 36 areprovided with inwardly extending flanges 37. Ateach corner each of thecaps 36 is a rectangular oillset socket 38 wherein the upper andlowerotlsots 12 and. 13 of the front and rear walls it) and 11 are seated.This is clearly illustratcd Figures l and 7. l Vithin the lower socket.)are provided inwardly extending anchoring lugs 39 between which and thewa ls of the sockets 3d the otl'sets 13 snugly lit, while the uppersockets 38 are likewise provided with inwardly exten ding flanges s'l)between which and the walls of the upper sockets 38 the offsets 12 aresnugly fitted and anchored. By the connections ust described the endcaps 36 find frictional engagement with the front and rear walls 10 and11, but to secure the latter permanently to the end caps 36 bolts 41 areprovided.

The head or each of the upper soclnats 38 is also grooved, as 42, forthe reception of the upwardly extending flanges 14-, of the front andrear walls 10 and 11, whereby a further interlocking engagement of? theWalls 10 and 1.1 with the end caps is el'lected.

At the inner side of the head of each oi? the er l caps 36 is located aboxlike receptacle said receptacle constituting a wiring box, and theinner wall. thereof has an opening e l therein which is surrounded by ahublihe e 45. The opening 4' receives one 0t 1 1e insulated lamp basesp1 musly (leso. ihcd :1 oil secured therein a so in the mannorhere..ibctore set forth. he up; 181, edge of said inner wall of thereceptacle .8 there is also provided flanged notches 46. Where only onewireway 30 is employed. illustrated in Figure 1,? and 8. one o f theflanged notches 46 receives the end of that wireway,

thus affording communication between the interior ot the receptacle i?)and the wircway 30. In such event the other flanged notch 4a; isclosedby the CllSjillitCeillOle closure web 47 which is seated in agroove 48, one of. these grooves being formed in each of the flangednotches 46. By the provision of said notches 46 either of the same maybe select-ed for locating the wireway 30 at either the front or the rearof the fixture, or both of the same may be utilized, if it be desired toemploy wiring connections for which one of the wireways is notsuflicient.

At the exterior of the inner wall of the receptacle a3 is positioned avertical rib 49 to which one of the fastening screws 32 is connected.thus providing means at the terminal portions of the fixture for holdingthe covering plate 33 in lixed relation to the end caps.

At the lower face of the base of the combined mullion and wiring box 17is provided a pair of grooves 50 into which the flanges 15 of the walls10 and ll are designed to fit so as to afford further anchorage of thesewalls with respect to the element 17.

It will be noted that the glass panels 16 are of greater width than theopening between the flanges 15 in order to overhang these flanges and besupportml thereby. and the ends of the panels 16 which lie contiguous tothe end caps 36 rest upon the bottom flanges 37 of these caps. If it bedesired to gain access to the interior of the fixture such may be easilyaccomplished by slightly elevating the end of the panel which liesadjacent to the head 18 of the combined mullion and wiring box,whereupon the panel may be moved over the bead, as illustrated by dottedlines in Figure 2. This permits access to the interior of the fixturefor such purposes as may arise, as for re-lamping the fixture.

In the use of the herein described fixture the same may be supportedfrom the bank screen by any suitable means which will clevate thefixture above the working plane of the desk or desks to be illuminated.The glass panels 1 6 afford a diffused light which is directedimmediately upon such working plane. Direct illumination thus isafforded. But in some circumstances it may be desirable for utilizingthe fixture for indirect illumi nation, in which event as shown inFigure 9, the cover plate 33 may be provided with openings 51 atsuitable points so that the rays of light from the lamps opposite theseopenings may pass out through the latter. In such construction thereflectors will be turned so as to direct the rays of light upwardlyrather than downwardly, and this arrangement may be followed so thatalternate lamps with their reflectors will project their rays throughthe top of the fixture, while the others project their rays downwardlythrough the glass panels 16 T he herein described invention provides afixture of sectional character which may be readily assembled, the partsbeinr so organized and inter-related as to permit their fitting togetherwith ease and minimum expense, and their production by instrumentalitiesand methods of manufacture entailing but little labor in suchproduction.
